A simple electric fan draws air through a water-soaked membrane, causing evaporation as the air comes into the living space.
You can construct a very simple but effective evaporative cooler yourself using a $20 box fan, a sheet of cooler membrane, a small water fountain pump, a small water bucket, a plastic tube, and a few pieces of 1-inch pine wood.
A commercially built swamp cooler will cost anywhere from $400 to $1,000, depending on if you have it installed or not.
This method of cooling uses a small fraction of the electricity that an air conditioner uses, and you have the added benefit of increased humidity, which is more comfortable for both humans and RVs.
Dry air causes wood to shrink and warp, which can cause all kinds of problems.
To give you a better idea of the costs involved, here's a rough estimate of the materials you'll need to build a simple evaporative cooler:
- $20 box fan
- $10 cooler membrane
- $5 water fountain pump
- $5 small water bucket
- $5 plastic tube
- $5 1-inch pine wood
Total estimated cost: around $50.

Drying Pads
To keep your swamp cooler in top shape, it's essential to dry the cooling pads regularly. This is done by running the swamp cooler on fan mode for 15–30 minutes at the end of each day.

The recommended time for drying the pads is between 15 and 30 minutes. This ensures the pads are completely dry before the next use.
You can't stress enough how important it is to dry the pads thoroughly. Moisture buildup can lead to mold and mildew growth, which can compromise the cooler's performance and even lead to health issues.
By following this simple maintenance routine, you'll be able to enjoy the benefits of your swamp cooler for years to come.
Alternatives and Considerations
If you're considering using a portable swamp cooler in your RV, you'll want to think about how it can work with your existing air conditioning system. In fact, you can use a swamp cooler as a back-up or when you're hooked up, and it's more cost-efficient, operating on as little as a $1 a day of electricity.
In hot weather, the balance between air temperature and humidity is crucial for human comfort. A swamp cooler raises humidity, which can be offset by the dehumidifying action of air conditioners, but finding the right balance is essential to avoid an overly dry or moist atmosphere.
You can save money on your monthly RV bill by using a portable swamp cooler, which uses much less electricity than traditional air conditioner units. This is especially true for RV-specific A/C units, where a swamp cooler can be a more affordable option.

What If I Have AC?
If you already have an AC in your RV, a portable swamp cooler can still be a great addition. It can work alongside your existing AC system as a backup or when you're hooked up to a power source.
You may find yourself running your evaporative cooler more often than your AC, especially during transitional times of the day. Running a swamp cooler during cooler parts of the day, such as early mornings or late evenings, can be adequate.
In very hot and dry climates, a swamp cooler might not suffice by itself. The air can become uncomfortably dry, and its cooling efficiency decreases as the outside temperature climbs above 100°F (38°C).
In these situations, an air conditioner can help manage the excess humidity produced by the swamp cooler. This can provide a more consistent cooling effect and maintain a comfortable environment inside your RV.
Here are some scenarios where combining a swamp cooler with your AC might be beneficial:
- Very hot and dry climates: A swamp cooler might not be enough on its own, but an air conditioner can help manage excess humidity.
- Transitional times of the day: Running a swamp cooler during cooler parts of the day can be adequate, but integrating air conditioning can help maintain a comfortable environment as the day heats up.
Keep in mind that using both systems together requires smart management, such as setting timers or using smart thermostats. This can help optimize energy use and make the most of your cooling systems.
Frequently Asked Questions
